EUGENE TULLER, OF STE. OROIX, SWITZERLAND, ASSIGNOR TOM. J. PAILLARD &00., OF NEWV YORK, N. Y.

MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 467,388, dated January19, 1892. Application filed November 10, 1891- Serial No. 411,467. (Nomodel.)

T at whom it may concern: Be it known that I, EUGENE TULLER, aciti zenof Switzerland, and a resident of Ste. Oroix, Switzerland, have inventedcertain new and useful Improvements in Music-Boxes, (for which I haveobtained a patent in Switzerland, No. 3,742,) of which the following isa specification.

This invention relates to improvements in music-boxes, and especially tomusic-boxes of that class known as interchangeable cylinder boxes, inwhich the cylinder can readily be removed and replaced by any cylinderprovided with pins for playing different tunes.

The object of my invention is to provide a box of this kind in which thecylinder can readily be removed and replaced, and in which no speciallocking devices for the cylinder are required.

The invention consists in the combination of the usual driving mechanismand pin-cylinder of bearings for the shaft of said cylinder, a boltoperated from the starting and stopping lever and serving to lock theshaft of said cylinder in place, and a bayonet-joint lock for that endof the shaft opposite the one locked by the bolt mentioned.

The invention also consists in the constructions and combination ofparts and details, as will be fully described and set forth hereinafter,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of the base-plateof myimproved 1n usic-boX and the driving mechanism on said base-plate,parts being broken out. Fig. 2 is a top View of the cylinder, parts ofthe same being broken out and the pins omitted. Fig. 3 is an end view ofthe cylinder. Fig. 4 is an end view of the base-plate, showing thedriving mechanism. Fig. 5is an end view of the cylinder andpower-transmitting mechanism and a side view of the flier andstop-lever. Fig. 6 is a side view of one of the bearings, showing themanner in which the latch locks the cylinder.

Similar letters of reference indicate corresponding parts.

On the base-plate A the springbarrel B is mounted, which is providedwith the usual winding lever and pawls. The gear-wheel B of saidwinding-barrel engages the pinion O,

mounted in lugs on the under side of the baseplate, and said pinion Cengages the pinion O, mounted on one end of the shaft D, journaled inlugs on the under sideof the baseplate. On the opposite end of saidshaft D a cog-wheel E is fixed, which is provided in its outer face witha circular groo e E, havinga notch E as shown in dotted lines in Fig. 5.From said cog-wheel E the retarding-fan F is driven in the usual manner,said fan being mounted to turn in the block G and arm G of said block.To the side of the said block G the locking-lever H is pivoted, the endH of said lever being adapted to engage an arm on the flier-shaft, andthe other end of said lever is provided with a pin H that is adapted totravel in the groove E of the cog-wheel E and to drop into notch E ofsaid groove. The lever H is also provided with an arm H to which ispivoted a sliding bolt or latch J that is guided in an aperture in theright-hand bearing K for the cylindershaft, and adapted to project overthe end part of the shaft when the same is within the notch of thehearing, as shown in Fig. 6. A spring I, attached to the arm H of thelever H and to the block G, serves to press the pin H against theinneredge of the groove E and into the notch E The bearing K is provided onits inner side with a laterally-projecting pin L, and the oppositebearing K is provided on its inner side with the laterally-projectingpin L. The cylinder M is mounted in the usual manner to slide on theshaft N, and is acted upon by the helical spriugN, surrounding the shaftand bearing against one end of the cylinder and against the sleeveO,n1ounted loosely on the shaft and provided with a longitudinal slot 0,into which the pin 0 projects from the shaft. Said sleeve 0 is providedwith an angular flange P,in the side of which a groove Q, having a notchQ, is formed. The shaftN is provided with a fixed cog-wheel R, that isadapted to engage the 5 cog-wheel E when the cylinder-shaft is placed inits bearing. Said cog-wheel R is provided in its outer face with a hubS, from which the two segmental lugs S S project and form the notch Sbetween them. The wheel R and the left-hand end of the cylinder areprovided with the handle-knobs T T The operation is as follows: XVhenthe mechanism is at a standstill, the pin 11 is in the notch E of thegroove E, and the bolt or latch J is withdrawn, as shown in Fig. 5. Thecylinder is seized by means of the handleknobs T T, and the ends of itsshaft are placed in the notches of the bearings K K, and rest on thebottom of said notches. Thereby the wheel R on the cylinder-shaft isengaged with the wheel E. In order to start the musical-box mechanism,the lever II must be so adjusted that the pin II is moved out.of thenotch E and the arm H is moved downward. This is accomplished by meansof the usual starting and stopping lever V, Fig. 1, thelaterally-projecting pin \V of which, when the musical box is to bestarted, acts on the arm H of the lever II and pushes the same in thedirection of the arrow X, Fig. 5, whereby the bolt or latch J is shiftedin the direction of the arrow X, and passes over that end of the shaft Nin the right-hand bearing K, as shown in Fig. 6, and thus automaticallylooks that end of the shaft in the bearing. When the cylinder-shaft isplaced into the bearings, the pin L of the left-hand bearing K passesthrough the notch Q into the groove Q on the flange of the sleeve 0, andthe pin L on the right-hand bearing K passes through the notch S betweenthe segmental lugs S. As soon as the cylinder begins to turn the pin Lprevents lifting the left-hand end of the cylinder-shaft, which is notlocked by a latch or bolt. \Vhen the cylinder has made one revolutionand completed a tune, the pin H automatically drops into the notch Epermitting the spring I to pull the lever H in the inverse direction ofthe arm X, whereby the latch or bolt J is drawn in the same direction,and thus releases the cylinder. As the cylinder has made one completerevolution, the notches S and Q will be directly below the pins L and L,thus permitting oflifting out the cylinder. The sleeve 0 is pressed bythe spring N against the pin L and at the same time presses the cylinderto the right, and the spring also presses the shoulders on theright-hand end to the cylinder-shaft against the bearing K, thus givinga perfectly true adjustment to the cylinder.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1 A music-box constructed with a removable cylinder and with a latchorbolt for looking said cylinder in its bearings, which look or bolt isoperated from the starting or stop-.

ping lever, substantially as set forth.

2. A music-box constructed with a driven wheel having a circular grooveand a notch in said groove, a locking-lever having a pin traveling insaid groove, and a bolt operated from said locking-lever, substantiallyas set forth.

3. In a music-box, the combination, with a base-plate, of bearings, acylinder having a shaft fitted in said bearings, a locking-levercontrolled by one of the Wheels of the driving-gear, and a boltconnected with said locking-lever, substantially as set forth.

4. In a music-box, the combination, with a base-plate and adriving-gear,one of the wheels of whichis provided with agroove andanotch in said groove, of a bolt or latch pivoted to said locking-leverand guided in one of the bearings of the pin-cylinder shaft,substantially as set forth.

5. In a music-box, the combination, with a base-plate, of the usualdriving-gear, a cylinder provided at one end of this shaft with a collarhaving a circular groove in its outer end and a notch in said groove, apin on the bearing adapted to enter said notch and groove, and a latchfor locking the opposite end of the cylinder-shaft in its bearing,substantially as set forth.

6. In a music-box, the combination, with a base-plate, of two bearingsfor the pin-cylinder shaft, a collar mounted on the pin-cylinder shaftand provided in its end with a circular groove and a notch, a pinprojecting from the bearing and adapted to enter said notch and groove,a locking-lever having a pin on one end, a driving-wheel having acircular groove and notch in which said pin ot' the locking-lever cantravel, and a bolt or latch pivoted to said locking-lever, substantiallyas set forth.

' In testimony that I claim the foregoing as my invention I have signedmy name in presence of two subscribing witnesses.
